Eberspächer auxiliary heaters for motorhomes and camper vans

Warmth and comfort wherever your wanderlust takes you

Fuel operated air or water heaters

Tailored to your personal traveling profile

Modern gasoline or diesel operated heaters for campers and motorhomes make traveling in your mobile home more pleasant and more comfortable. They combine many advantages in a small footprint: they are extremely quiet, don’t use much fuel or electricity, can be controlled with precision, and can also keep the vehicle interior warm and cozy while you’re driving.

Diesel/gasoline or propane?

If you’re camping in the winter, 80% of the propane you use is needed for propane heating. So you always need to keep your motorhome stocked up with propane. With a fuel operated heater, you no longer need to do this, because it is supplied from the vehicle tank and is very frugal. This way, you save on weight and gain a lot of valuable storage space. At the same time, you’re more independent on the road, as you don’t have to keep worrying about finding suitable propane bottles with the right adapter, which can very often be a logistical challenge when you’re abroad.

What counts when making your selection from Eberspächer’s extensive heater range is your personal heating needs – which depend on your vehicle, your travel destinations and habits, and how you intend to use the auxiliary heater.

The following questions are an initial aid to your decision-making:
How big is the space I want to heat? Am I only going to use the heater as additional heating? Do I want to be able to warm up the interior spontaneously and quickly? Do I want to heat the tap water (boiler, shower) as well?  Are a pre-heated engine and de-iced windows important to me? Do I spend long periods in very cold climates? Do I simply want to extend the travel season into spring and fall/winter? Does the heater also have to function at high altitude? How big is the installation space?

The table below provides some initial guidance:

I need heating in the front area, e.g. in the area of the lift bed

We recommend: Airtronic S3 Commercial air heater

I need fast and independent heating in the living area, including the front area

We recommend: Airtronic M3 Commercial or Airtronic M3 Recreational air heater

I need de-iced windows, pre-heating to protect the engine and rapid heating via control fittings

We recommend: Hydronic water heater

I would like a constantly warm interior via fan convectors or underfloor heating and/or diesel operated tap water heating in connection with a boiler

We recommend: Hydronic water heater
